Cartier Rotonde de Cartier Flying Tourbillon 18K White Gold Silver Dial

The Cartier Rotonde de Cartier Flying Tourbillon reference W1556216 presents a 40 mm 18‑carat white gold round case measuring approximately 10.6 mm thick, distinguished by its beaded crown set with a sapphire cabochon and a fixed white gold bezel. The silvered, open‑worked guilloche dial features black transferred Roman numerals and blued‑steel sword‑shaped hands, with the flying tourbillon visible at 6 o’clock via a C‑shaped carriage that also indicates seconds. Powered by the manually wound Cartier caliber 9452 MC—Geneva Seal certified, comprising 142 components and 19 jewels, beating at 21,600 vph with a power reserve of about 50 hours—the movement is visible through a sapphire display back. The watch is fitted with a black alligator leather strap secured by an 18 K white gold double‑deployant clasp and offers 30 meters of water resistance. This specific reference is known to have been introduced around 2012 and is no longer in production, making it a refined example of Cartier’s haute horlogerie in a discreet yet technically compelling configuration. Excellent Condition with Cartier box and undated papers.
